City of Boulder Resources

The City of Boulder offers an online property search tool on its website that you can use to get information on properties located within city limits. Searches are conducted by address and return two types of reports: a property report and an enforcement summary report. The property report is linked to the parcel number and includes official details about the land and structures, while the enforcement summary report is linked to the address and lists any past or current code enforcement actions, such as violations, complaints, or notices. Together, these reports give a full picture of both the property's official records and any compliance issues associated with it.

Boulder property taxes are used to fund various local services, including public schools, police and fire departments, emergency services, road maintenance, libraries, parks and recreation, and public transportation. The Boulder County Assessor identifies, classifies, and values properties, while the Boulder County Treasurer calculates tax bills and collects payments based on those assessments. Property values are reassessed every two years (in odd-numbered years), and property taxes are billed one year in arrears. This means that the tax you pay in the current year is actually for the previous year's obligation.

Property tax bills are typically mailed out by late January each year. Payments can be made in full, due by April 30th, or in two equal installments, with the first payment due by February 28th and the second payment due by June 15th. Partial payments are not accepted, and there are no discounts for early payment. Late payments will also accrue monthly interest plus additional penalties. If the taxes remain unpaid, the county may place a tax lien on the property and eventually enforce collection through an annual tax lien sale. The Boulder County Treasurer's Office provides several options for paying your property taxes, including online, by mail, and in person. You can call (303) 441-3520 for additional information and assistance.

Assessments

The Boulder County Assessor's Office conducts assessments to determine the taxable value of real property in Boulder. Property values are determined using mass appraisal methods, including the sales/market approach (reviewing comparable sales), the cost approach (estimating replacement cost), and the income approach (evaluating income potential for rental or commercial properties). Once a property's market value is established, it is multiplied by a state-mandated assessment rate to calculate its taxable value, which is then used to determine the final tax bill. Property values are reassessed every two years in odd-numbered years. During the even-numbered years between reassessments, the property's taxable value generally remains unchanged unless there has been a physical change, change in use, or other qualifying adjustment that affects its value.

Property owners typically receive a notice of valuation by early May of reassessment years, though a notice may also be issued between cycles if there is a significant change to the property. If you believe your property's valuation is inaccurate, you may file an appeal with the Boulder County Assessor's Office. The official appeal period typically runs from May 1st to June 9th, and appeals can be submitted online, by mail, or in person (instructions are usually provided on the notice itself). You can call the assessor's office at (303) 441-3530 for assistance or inquiries.

Appraisals

Boulder assessments work similarly to appraisals. They both determine the fair value of property by comparing similar properties with others in the local area that have sold recently. In cases of odd structures or new construction, the county may call upon an appraiser to help determine the value. Estate planners, courts, and lenders also use appraisals to value real property.
